BURNER.

risicos..

Application filed September 3, 1915.

To all whom t may concern Be it known that I, NICHOLAS W. AN- THONY, of the city, county, and State of New York, have invented certain new and useful Improvements in Burners, of which the following is a specification.

rIhis invention relates to liquid hydrocarbon burners and more particularly to burners designed for use in connection with boiler and metallurgical furnaces.

The objects of the invention are to pro- Vide a burner of the low air pressure type having large capacity and in which a multiplicity of fuel jets are employed and the flow of air regulated at the nozzles by a device which is common to all of the nozzles.

A further object of the invention is to provide a burner of the low air pressure type having a high efficiency as well as large j heat generating capacity.

A further object of the invention `is to provide a burner of simple construction which may be readily taken apart or put together in accordance with the necessities of actual practice.

Other objects and the features of novelty will be apparent from the following descrip-p tion. Fig. 2 is a section on line 2-2 of Fig.` l. Fig. 3 is a longitudinal section of an-l other form of the invention. Fig. 4 is a section on line 4 4 of Fig. 3, and Fig. 5 is a fragmentary section of a modification of one of the details. Fig. 6 is a longitudinal section of still another form of the invention,

Referring to Fig. 1, 10 indicates the casing which is provided with the air pipe connection 11 and a removable plug 12, the latter being at the rear of the casing and carrying the fuel conduit 13. Within the casing 10, the conduit 13 is enlarged as shown at 14 and has connected therewith a plurality of pipes or nozzles 15 which discharge the fuel to the exterior of the casing, through the plugs or nebulizers 16. The nebulizers are secured in a ring 17, which connects the ends of the nozzles 15 and is spaced from the wall of the casing 10 to provide the an-l nular air passage 18. The ring 17 also has a central opening 19 for the discharge of Specification of Letters Patent.

. The cap 20 deflects the air from the passage 18 substantially at right angles to the fuel spray from the nebulizers 16, so that an annular liame will be formed, the air supplied A through the central opening 19 supporting .combustion on the interior of the iame. In this way it is possible to supply the air at low pressure and provide the requisite quantity to burn the fuel with the maximum efciency.

In the form of the invention shown in Figs. 3 and 4, the plug 22 at the rear of the casing 10 is formed with a tubular extension 23 on the interior of the casing and to this extension there is secured a nozzle member comprising a hollow ring 24 and the branch pipes 25 which are adapted to convey the fuel from the interior of the extension 23 to the space 26 on the interior of the ring 24. rIhe ring 24 carries a series of nebulizers 27, as many nebulizers being employed as the size of the ring 24 permits. The ring 24 is spaced from the casing 10 to provide the annular air passage 28 and may be provided with openings 29 between the nebulizers for the purpose of permitting the passage of air from the interior of the casing. The central opening 30 in the ring 24 provides for the supply of a large volume of air in front of the burner and in order to increase the efli ciency of the burner an outwardly flaring deflector 31, having a screw thread connection with its support 25 whereby it may be adjusted, is arranged in the opening 30, and directs the air substantially at right angles to the inner surface of the ring of spray from the nebulizers 27. The adjustable cap I 30v on the casing has an inturned flange 30 which directs the air from the passage 28 against the spray from the nebulizer 27 and in every lparticleof fuel receiving the requisite'supply of air for the maximum eliciency of combustion.

. The modification shown in Fig. 5 has the 5 outwardly flaring deliector 32 carried by the ring 24a and preferably formed integral therewith by means of the ribs 33. This deflectorjperforms exactly the same function as the deflector shown in Fig, 3. I

In the modification shownV in Fig. '6 jthe rear plug 34: is made hollowand the noz- 'zfles 35 receive fueltherefrom. /Tli'eringfat theouterendfof lthe other forms `is.on1'itted but a central `"deflecto'r 36 having a screw 15 'thread connection With 2theplug 34 Where- Eby it be adjusted is preferably pro- =vided. "The omission of tthe annular avoids having a mass of metal `at the diseharge *end VWhere it retards the flow .ofV jair and, 4becoming hot, heats vup'the ffu'el. YThe 'floW jof air through, the burner, .shown 'in Fig. "6,lcools the 'nozzles andb'y 'maintaining thesup]` oly, forthe nozzles, in the Ihead 34, "theoil is 'kept farther lzvay V"from "the liame anuleannctbecomeltoo het. i It yv-ill be evident from the drawings and I'the foregoing "description that 'numerous arrangements jfof thein'bulizers "and :air lpasvsages rna'y "be fprovided 'Without Jdeparting jfrom the spirit of the invention 'as defined inthe claims andftherefore *do nctwishfto limit the inilentio'n to the 'eXact details of ".eonstruotion shown "and described.
